Question
A shopkeeper marked an article P% above its cost price
and sold it for Rs. 480 after giving a discount of 20%. If the ratio of cost price and selling price of the article is 25:30, respectively, then find the selling price if the article is sold at a profit of (P + 8)%.Solution
Cost price of the article = (25/30) × 480 = Rs. 400 Marked price of the article = 480/0.8 = Rs. 600 P% = [(600 – 400)/400] × 100 = 50% Or, P = 50 Desired selling price = 400 × 1.58 = Rs. 632
